Ladder ring to spread by Britain quality one that Company develop new-type to turn on pass packing. Its makes an appointment for half of the diameter high in the ring of the ladder( CMR), there are toper turn-ups on the side, Openings in a wall are held on the ring wall, and have crooked blades to stretch to the ring heart. Reduce highly and toper special structure of turn-ups, improve packing layer angry liquid is distributed, And has increased the angry liquid and keep in touch and is clicked, help the liquid to assemble dispersing and continual renovation with superficial membrane, Enable spreading the quality and is strengthened, separate efficiency to improve greatly . The general ladder surrounds the packing relatively the flux that Ball surrounds the packing can be improved by 10-20%, press and reduce by 30-40%, Separating efficiency has improvement in various degree to look at the concrete craft. Up till now, already more than 1000 ladders have surrounded the packing tower to absorb in the whole world. The vapour steams the application while operating with distillation,etc.. According to the concrete conditions, the ring of the ladder can be taken the place of and draw the west ring, Ball's ring, Steep and cover the board, the floating valve board and sifting the board, it is high-efficient to reach, High yield and energy-conserving purpose. Sea salt petrochemical industry factory according to the People's Republic of China production, HG/T21557-95 of sector standard,, its characteristic parameter the following form show:

Form 1: The steel ladder of carbon surrounds the characteristic parameter of the packing
